2.8.3 PROGRAM INTERRUPTION ON/OFF
(M91 , M90) t
The following M codes are used for the program
interruption function .
Program interrupt function OFF
N o t e : When power is applied or the control is
reset, the control is in the state of M code
marked with
P. . . . . . ;
During the time from this command to an M90
command, whenever a program interruption
signal is received, the program under
tion is interrupted (if the machine is in motion,
it is stopped after deceleration) , and the a jump
is made to the program the number of which is
written after the
.
.
With this command, the program interrupt func-
tion is
2.8.4 MULTI-ACTIVE REGISTERS ON/OFF

.
M93:
During the time from this command to M92, the
control assumes the 4 blocks-advance-reading
mode.
Namely, up to 4 blocks of data are read
in advance for the following operation.
Inter-block stoppage can be eliminated when
the program is so made that the operation time
of advance reading of 4 blocks is longer than
processing time of advance reading of next 4
blocks of data.
M92:
This command cancels 4 blocks-advance -reading
mode.
Note : In tool radius compensation C mode, the
blocks without move command can be contained( up to
two blocks ) .
Under this condition, 6 blocks, in-
cluding the two blocks, may be read in advance.
2.8.5 MIRROR IMAGE ON/OFF M94)
M code Meaning
I
M94 Mirror image OFF
M95 Mirror image ON
Note: When power is applied or the control is
reset, the control is in the state of M code
marked
With these codes, mirror image operation can
be started and stopped at any desired point in
the program.
These commands must always be
made on a single block,
M94 and M95 are modal. When the power supply
is turned on, M94 (OFF) is in effect.
The axis on which mirror image is to be effected is
specified by setting #6000 Do to D3 (or mirror image
axis designation switch). For this procedure, refer to
5.1.25, “MIRROR IMAGE AXIS
SWITCH”
on page 171.
W h e n is given, the subsequent blocks will
control the machine in mirror-image fashion,
that is, movements in the specified coordinate
direction will be reversed.
